Features of i.Series Upright -50ºC to -86ºC Ultra-Low Temperature Freezers

Unique Heat Barrier System Hot Gas Loop Anchors Frame and Cabinet Design
The system is designed with a fortified outer door with 3 heavy-duty adjustable hinges; a multi-bulb polygonal gasket compresses for a compact sealing surface and a cast aluminum single-handed door handle.

Insulated inner doors maintain cabinet temperature to prevent frost build-up. Temperature fluctuations are minimized via the structurally reinforced insulated design. The dual-blade gasket systems stops warm air from entering between the inner doors and multiple doors provide easy access to specific samples without exposing other samples. Swing-outs are also prevented with a positive latching inner door.
The unit is designed with an ice-resistant sealing surface to achieve a better seal that improves temperature uniformity and minimizes interior frost formation.
  • Energy-efficient hot gas loop for a frost-free door frame
  • Advanced composite panels reinforces the cabinet and reduces the amount of heat transfer
Single-handed Door Handle Multi-point Gaskets
The ergonomic door handle is made of heavy-duty, cast aluminum and hardened steel and the smooth one-handed design that includes a key lock and padlock hasp that enables operators to secure valuable samples. The i.Series uses multi-bulb, polygonal gaskets on the outer doors that compress against the frame and forms a tight seal. This prevents moisture from migrating and keeps heat out and reduces frost build-up. There is also a dual-blade gasket between the inner doors as an added prevention measure to prevent warm air from entering the chamber
Premium Insulation Optimum Oil Management for Greater Reliability
The i.Series focuses on preventing frost build-up and that is achieved by the use of premium insulation that ensures stable temperature uniformity.
  • Premium insulation panels are used in all outer doors and in 18 and 26 cu ft. cabinets
  • Combined with traditional EcoMate™ foaming-place insulation, the cabinets provide a precision temperature environment for the long-term preservation of specimens and components in laboratories and hospitals
The maximum heat exchange and optimized oil management of the i.Series reduces stress on the compressor resulting in increased freezer reliability. The specially engineered oil separator removes all oil from the refrigerator lines and the mixed refrigerant has been optimized to ensure proper flow rate at extremely low temperatures.

Optimum heat exchange pathways evenly and thoroughly cools the cabinet with a split evaporator.
